Three patterns of posterior plane of lenticule were noticed when the surgical videos were re-watched. A \u201cdouble lines\u201d attached to the dissector were visible, signifying the reflective tape of the edge of the lenticule and the cap. During the expansion of the posterior lamellar separation, a fusiform opening between the lenticule edge and the underlying matrix layer was assumed to be a \u201cleaf sign.\u201d With some unintentional operation, the posterior lamella was pushed away from the surgeon. The edge of the lenticule away from the anatomical part, the marking of the femtosecond laser cut, and the edge of the cap layer showed three reflective bands, which formed a \u201ctriple lines.\u201d The \u201cdouble lines,\u201d \u201cleaf sign,\u201d and \u201ctriple lines\u201d were observed in 30 eyes (57.7%), 21 eyes (40.4%), and 1 eye (1.9%), respectively.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>These three signs cover possible situations and provide visual landmarks to identify the correct dissection of the posterior plane, which can help shorten the learning curve of novice doctors.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1007\/s10792-023-02760-9","type":"journal-article","created":{"date-parts":[[2023,6,24]],"date-time":"2023-06-24T08:16:58Z","timestamp":1687594618000},"page":"3533-3538","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Three patterns for identifying the posterior plane of a lenticule during SMILE"],"prefix":"10.1007","volume":"43","author":[{"given":"Ke","family":"Zheng","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jing","family":"Wang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiaohong","family":"Zheng","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yinan","family":"Han","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xingtao","family":"Zhou","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2023,6,24]]},"reference":[{"issue":"2","key":"2760_CR1","doi-asserted-by":"publisher","first-page":"362","DOI":"10.1038\/s41433-020-1096-5","volume":"35","author":"M Ang","year":"2021","unstructured":"Ang M, Gatinel D, Reinstein DZ, Mertens E, Ali\u00f3 Del Barrio JL, Ali\u00f3 JL (2021) Refractive surgery beyond 2020.
